With the great Auto Complete, it is very efficient to find and insert a tiddler. Only one inconvenience is not to list tiddlers by relevant even the exact title is typed when there are many similar tiddlers.
For example, I want to find a tiddler Frost Stress, but list all others. I have used arrow key to find the one I need.

The rsort operator by @clsturgeon sounds very useful here.
Then I modified filter for All tiddlers in auto complete plugin through add rsort<query> at the end.
[all[tiddlers]!is[system]!has[draft.of]search:title<query>rsort<query>]
Now it is much easier to find a tiddler I need.

Step to reproduce
- download rsort from http://craigsturgeon.com/mk/example/Churchill-Example.html#%24%3A%2Fplugins%2Fcls%2Fmk%2Fmodules%2Ffilters%2Frsort.js
- import download json file your tw files with force refreshing to load js file.
- modify
filterin your triggers through addrsort<query>
